Moving To Milan for A Year

My name is Tracy Castro and will be moving to Milan on December 30th. I will be attending Universita Cattolica for a specialized masters January-December. Therefore, I am looking for a long-term lease near in the city center. Unfortunately, I am having a difficult time finding online real estate sites to secure housing abroad. Does anyone have any suggestions? I wouldn't mind renting just a room. If you know anyone that needs a flatmate, please let me know. Or if you have any suggestions on where to look please send it my way.
